The present invention provides a sideframe for use in a traditional three piece railway fright car truck comprising a pair of laterally spaced sideframes supporting a bolster extending between the sideframes. Each sideframe comprises an elongated top compression member, two diagonal compression members extending generally downwardly at acute angles from near the ends of the top compression member, and a bottom member joining the other ends of the diagonal tension members. Two column members also extend vertically between the bottom member and the top compression member. Pads with fastener openings are provided on the top surface of the top compression member to assist in mounting brackets to the sideframe.
La présente concerne un longeron destiné à un wagon conventionnel à trois éléments, qui se compose d'une paire de longerons latéraux espacés qui supportent une traverse qui relient les longerons. Chaque longeron comprend un élément supérieur de compression en longueur, deux éléments de compression diagonaux habituellement orientés vers le bas à fort angle, à partir des extrémités de l'élément de compression supérieur, ainsi qu'un élément inférieur qui relie les autres extrémités des éléments de tension en diagonale. Deux montants verticaux relient l'élément inférieur et l'élément de compression supérieur. Des cales munies d'orifices de fixation garnissent la face supérieure de l'élément de compression supérieur, afin de permettre la pose de supports de montage sur le longeron.
